Be =nown that I CHARLES BAYLY 7 M a subject of the King of Great Brit in. iding at Springfield, in the ounty of Hampden, State of Massachusetts, are invented certain new and useful Im- -.'lIlilfS in Kick-Starter Supports, of 'ch the following is a description, referbeing had to the accompanying drawingand to the figures of reference marked thereon.

Heretofore the supporting structure for starting cranks of motorcycles has not been sufliciently rigid and strong. In prior constructions it has been the practice to support the starting crank by forming a bearing therefor in the wallet the transmission case carried by the cradle and to support the lower end of the seat-post from a cross raine carried behind the case by the side f zines of the cradle. \Vhile this construction has been a distinct advance in frame construction. its principal objection lay in the fact that the casing wall did not provide a suiliciently strong bearing. I The principal object of this invention is to provide a strong and durable bearing for this lriclr starting'crank by supporting it directly from the cradle.

rrnother feature of the-invention resides in forming l special support adapted to be attached to the cradle. which support is formed with a bearing for the starting crank. and also with a means for connection with the lower end of the seat-post. This construction not only prov-ides a sturdy bearing for the kick starter and for the seat-post,

but also positions the kick starter substantially under the seat-post which is a more desirable location for securing an effective operation from the driving seat.

Still another feature of this invention re- 5 sides in 'providing'means 'for bolting this special frame or upright to the rear of the transmission casing whereby not only to form a firmer intersupportfor these two members but also to provide a sure and positive means for determining the distance between the starting crank journal on which the starting sector is mounted and the projecting end of the transmission shaft on which the gear meshing with the sector is mounted. I

A further feature of the invention resides providing a special support for the ;kicl

obvious and will in part be hereinafter more fully disclosed. I

Referring more particularly to the accompanying drawing c Figure 1 is 'a perspective view of the improved supportdthe transmission case beingshown in dotted lines;

4 2 is a perspective rear view of the support;

Fig. 3 is a view similar to Flg. lwofvthe support used when the machine is to be equipped with a starter on either side, and t is a detached view of the support. lngeneral; the invention comprises a separate, comparatively short standard or up right; the base of which straddles the-paral- I lel side frames of the cradle being permanently attached thereto as by brazing. The upper portion of the standard is formed as a hollow sleeve adapted to form a supporting seat for. the lower endof the seat post which is brazed therein. while the interme diate portion of the standard is formed as a laterally projecting bearing for the starting crank stud. The front of the upright is provided with a lug by which it may be bolted to-the rear of the transmission "case. In this manner, the case and the standard. mutually support each otherwhile the distance between them andhence between the sector and transmission shaft journals is definitely fixed.

Regarding the drawing in detail the main frame -or cradle includes the two parallel side members ortubes 1 and 2 on which the transmission case 3 shown in dotted lines is mounted as usual; Immediately to the .rear' case as shown in dotted lines in the draw spring 15 is coiled about the journal and is suitably attached to the support and sector at its opposite ends so as to normally swing the sector clear of the transmission gear journaled on the outsid of the transmission In order to rigidly interconnect the case and the upright, the latter is formed in front with an integral lug l6 bored vertically as at 17 to receive a bolt likewise passing through a lug on the rear of the transmission case. By this means, the distance between the ournals for the sector and the intermeshing transmission gear are accurately determined.

Figures 3 and 4 illustrate a slight modification of the bearing as arranged so that a machine can be equipped with a starter operable from either side of the machine. In this construction, the intermediate bearing is arranged symmetrically to project laterally on both sides of the upright and is bored entirely through to receive, as desired, a long or short pin or stud. W

Figure 3 shows the short pin used, in this arrangement, as in Fig. 1, the sector and foot pedal are mounted on the same end of the pin. Fig. 4 shows the long pin 19 passing through the hearing. In this construction, the foot pedal 20 is attached to one end of the pin and the toothed sector is attached to the other, so that the machine can be started from the lefthand side. Figures 3 and 4: also show the baserof the upright formed with integral bearings 22 and 21 arranged on the sleeves 23 and 24. These bearings are bored to receive a transverse rod 25 to the opposite ends of which are fixed cranks 26 and 27 connecting with the forward and rearward rods for operating the brake mechanism. Obviously, these bearings and the rod 25 may be omitted if desired.

It will be obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters-Patent, is-

1. In a motorcycle, the combination with the cradle and transmission case carried thereby, an upright supported by said cradle rearwardly of saidcas and provided with a bearing, a toothed sector, and kick-starter lever journaled in said bearing, said sector adapted to mesh with a gear j ournaled in the transmission case.

2. In a motorcycle, the combination with the cradle and a transmission case carried thereby, an upright supported by said cradle rearwardly of said case and provided. with a bearing, means for connecting said upright to said case to hold the same in fixed relation thereto, a toothed sector and kickstarter lever journaled in said bearing, said sector adapted to mesh with a gear journaled in said transmission case.

3. A kick-starter support for a motorcycle comprising an upright having a base adapted to be supported by the side frames of the cradle, said upright being formed at its upper portion to support the lower end of the seat-post and also'provided with a bearing for supporting the starting crank sector and foot lever.

4. A kick-starter support for a motorcycle of the seat-post, and an intermediate bearing for the kick-starter sector and foot lever.

55. A kick-starter support for a motorcycle comprising an upright having a transverse base provided with bearings adapted to be connected to the side frames ofjthe cradle,

said upright being formed at its upper por-,

tion to support the lower end of the seat post and with a bearing for supporting the starting crank sector and foot lever, said base bearings also being formed with additional bearings for supporting the brake operating control rods.

In testimony whereof, I affix my signature.

' CHARLES BAYLY FRANKLIN.
